| CVE-2022-49961 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-06-01 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Do mark_chain_precision for ARG_CONST_ALLOC_SIZE_OR_ZERO Precision markers need to be propagated whenever we have an ARG_CONST_* style argument, as the verifier cannot consider imprecise scalars to be equivalent for the purposes of states_equal check when such arguments refine the return value (in this case, set mem_size for PTR_TO_MEM). The resultant mem_size for the R0 is derived from the constant value, and if the verifier incorrectly prunes states considering them equivalent where such arguments exist (by seeing that both registers have reg->precise as false in regsafe), we can end up with invalid programs passing the verifier which can do access beyond what should have been the correct mem_size in that explored state. To show a concrete example of the problem: 0000000000000000 <prog>: 0: r2 = *(u32 *)(r1 + 80) 1: r1 = *(u32 *)(r1 + 76) 2: r3 = r1 3: r3 += 4 4: if r3 > r2 goto +18 <LBB5_5> 5: w2 = 0 6: *(u32 *)(r1 + 0) = r2 7: r1 = *(u32 *)(r1 + 0) 8: r2 = 1 9: if w1 == 0 goto +1 <LBB5_3> 10: r2 = -1 0000000000000058 <LBB5_3>: 11: r1 = 0 ll 13: r3 = 0 14: call bpf_ringbuf_reserve 15: if r0 == 0 goto +7 <LBB5_5> 16: r1 = r0 17: r1 += 16777215 18: w2 = 0 19: *(u8 *)(r1 + 0) = r2 20: r1 = r0 21: r2 = 0 22: call bpf_ringbuf_submit 00000000000000b8 <LBB5_5>: 23: w0 = 0 24: exit For the first case, the single line execution's exploration will prune the search at insn 14 for the branch insn 9's second leg as it will be verified first using r2 = -1 (UINT_MAX), while as w1 at insn 9 will always be 0 so at runtime we don't get error for being greater than UINT_MAX/4 from bpf_ringbuf_reserve. The verifier during regsafe just sees reg->precise as false for both r2 registers in both states, hence considers them equal for purposes of states_equal. If we propagated precise markers using the backtracking support, we would use the precise marking to then ensure that old r2 (UINT_MAX) was within the new r2 (1) and this would never be true, so the verification would rightfully fail. The end result is that the out of bounds access at instruction 19 would be permitted without this fix. Note that reg->precise is always set to true when user does not have CAP_BPF (or when subprog count is greater than 1 (i.e. use of any static or global functions)), hence this is only a problem when precision marks need to be explicitly propagated (i.e. privileged users with CAP_BPF). A simplified test case has been included in the next patch to prevent future regressions. | ||||
| CVE-2026-27289 | 1 Adobe | 2 Photoshop, Photoshop Desktop | 2026-06-01 | 7.8 High |
| Photoshop Desktop versions 27.4 and earlier are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. | ||||
| CVE-2026-5071 | 2 Zephyrproject, Zephyrproject-rtos | 2 Zephyr, Zephyr | 2026-06-01 | 6.1 Medium |
| The SocketCAN implementation validates the length of a user-provided buffer containing a socketcan_frame object using only a NET_ASSERT statement in zcan_sendto_ctx() before dereferencing it in socketcan_to_can_frame(). In production builds where assertions are disabled, a userspace application that controls the length passed to a sendto syscall can supply an incomplete or truncated frame, causing socketcan_to_can_frame() to dereference fields beyond the end of the buffer. This results in an out-of-bounds read that can cause denial-of-service crashes or, because the parsed frame contents are transmitted on the network, leak adjacent memory. | ||||
| CVE-2026-39929 | 1 Lakesidesoftware | 1 Systrack Agent | 2026-05-30 | 7.5 High |
| Lakeside SysTrack Agent versions prior to 11.2.1.28, 11.3.0.38, 11.4.0.24, 11.5.0.15 contain an out-of-bounds read vulnerability in the Command ID 30 UDP packet handler that allows remote attackers to crash the application by sending a specially crafted UDP packet. Attackers can send a malformed packet with an invalid memory address at offset 0x4 in the payload to trigger an access violation and cause a denial of service. | ||||
| CVE-2026-46204 | 1 Linux | 1 Linux Kernel | 2026-05-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: Prevent OOB reads when parsing IB Rewrite the IB parsing to use amdgpu_ib_get_value() which handles the bounds checks. | ||||
| CVE-2026-46138 | 1 Linux | 1 Linux Kernel | 2026-05-30 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: Fix OOB read and infinite loop in hci_le_create_big_complete_evt hci_le_create_big_complete_evt() iterates over BT_BOUND connections for a BIG handle using a while loop, accessing ev->bis_handle[i++] on each iteration. However, there is no check that i stays within ev->num_bis before the array access. When a controller sends a LE_Create_BIG_Complete event with fewer bis_handle entries than there are BT_BOUND connections for that BIG, or with num_bis=0, the loop reads beyond the valid bis_handle[] flex array into adjacent heap memory. Since the out-of-bounds values typically exceed HCI_CONN_HANDLE_MAX (0x0EFF), hci_conn_set_handle() rejects them and the connection remains in BT_BOUND state. The same connection is then found again by hci_conn_hash_lookup_big_state(), creating an infinite loop with hci_dev_lock held. Fix this by terminating the BIG if in case not all BIS could be setup properly. | ||||
| CVE-2026-45935 | 1 Linux | 1 Linux Kernel | 2026-05-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix slab-out-of-bounds read in DeleteIndexEntryRoot In the 'DeleteIndexEntryRoot' case of the 'do_action' function, the entry size ('esize') is retrieved from the log record without adequate bounds checking. Specifically, the code calculates the end of the entry ('e2') using: e2 = Add2Ptr(e1, esize); It then calculates the size for memmove using 'PtrOffset(e2, ...)', which subtracts the end pointer from the buffer limit. If 'esize' is maliciously large, 'e2' exceeds the used buffer size. This results in a negative offset which, when cast to size_t for memmove, interprets as a massive unsigned integer, leading to a heap buffer overflow. This commit adds a check to ensure that the entry size ('esize') strictly fits within the remaining used space of the index header before performing memory operations. | ||||
| CVE-2026-45856 | 1 Linux | 1 Linux Kernel | 2026-05-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/uverbs: Validate wqe_size before using it in ib_uverbs_post_send ib_uverbs_post_send() uses cmd.wqe_size from userspace without any validation before passing it to kmalloc() and using the allocated buffer as struct ib_uverbs_send_wr. If a user provides a small wqe_size value (e.g., 1), kmalloc() will succeed, but subsequent accesses to user_wr->opcode, user_wr->num_sge, and other fields will read beyond the allocated buffer, resulting in an out-of-bounds read from kernel heap memory. This could potentially leak sensitive kernel information to userspace. Additionally, providing an excessively large wqe_size can trigger a WARNING in the memory allocation path, as reported by syzkaller. This is inconsistent with ib_uverbs_unmarshall_recv() which properly validates that wqe_size >= sizeof(struct ib_uverbs_recv_wr) before proceeding. Add the same validation for ib_uverbs_post_send() to ensure wqe_size is at least sizeof(struct ib_uverbs_send_wr). | ||||
| CVE-2026-43070 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register ID for BPF_END value tracking When a register undergoes a BPF_END (byte swap) operation, its scalar value is mutated in-place. If this register previously shared a scalar ID with another register (e.g., after an `r1 = r0` assignment), this tie must be broken. Currently, the verifier misses resetting `dst_reg->id` to 0 for BPF_END. Consequently, if a conditional jump checks the swapped register, the verifier incorrectly propagates the learned bounds to the linked register, leading to false confidence in the linked register's value and potentially allowing out-of-bounds memory accesses. Fix this by explicitly resetting `dst_reg->id` to 0 in the BPF_END case to break the scalar tie, similar to how BPF_NEG handles it via `__mark_reg_known`. | ||||
| CVE-2021-41556 | 2 Fedoraproject, Squirrel-lang | 2 Fedora, Squirrel | 2026-05-29 | 10 Critical |
| sqclass.cpp in Squirrel through 2.2.5 and 3.x through 3.1 allows an out-of-bounds read (in the core interpreter) that can lead to Code Execution. If a victim executes an attacker-controlled squirrel script, it is possible for the attacker to break out of the squirrel script sandbox even if all dangerous functionality such as File System functions has been disabled. An attacker might abuse this bug to target (for example) Cloud services that allow customization via SquirrelScripts, or distribute malware through video games that embed a Squirrel Engine. | ||||
| CVE-2026-23269 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 7.1 High |

| CVE-2026-45615 | 1 Mouse07410 | 1 Asn1c | 2026-05-29 | 8.2 High |
| mouse07410/asn1c is an ASN.1 compiler. In 1.4 and earlier, a memory safety vulnerability was identified in the OER decoding skeleton files generated by asn1c (specifically INTEGER_oer.c). When parsing a maliciously crafted, zero-length OER payload for a variable-length, non-negative INTEGER type, the decoder fails to validate the required bytes before extracting the Most Significant Bit (MSB). This forces a precise 1-byte Heap Out-of-Bounds (OOB) Read. Because asn1c generated code is primarily deployed to parse untrusted network inputs (such as V2X network protocols, 5G telecom headers, or X.509 certificates), when the decoder processes untrusted network-originated input, a remote attacker can exploit this to cause a Denial of Service (DoS) or trigger incorrect integer interpretation in downstream applications (e.g., protocol state poisoning or logic bypass). | ||||
| CVE-2026-23288 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix out-of-bounds memset in command slot handling The remaining space in a command slot may be smaller than the size of the command header. Clearing the command header with memset() before verifying the available slot space can result in an out-of-bounds write and memory corruption. Fix this by moving the memset() call after the size validation. | ||||

| CVE-2025-71306 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: ima: Fix stack-out-of-bounds in is_bprm_creds_for_exec() KASAN reported a stack-out-of-bounds access in ima_appraise_measurement from is_bprm_creds_for_exec: BUG: KASAN: stack-out-of-bounds in ima_appraise_measurement+0x12dc/0x16a0 Read of size 1 at addr ffffc9000160f940 by task sudo/550 The buggy address belongs to stack of task sudo/550 and is located at offset 24 in frame: ima_appraise_measurement+0x0/0x16a0 This frame has 2 objects: [48, 56) 'file' [80, 148) 'hash' This is caused by using container_of on the *file pointer. This offset calculation is what triggers the stack-out-of-bounds error. In order to fix this, pass in a bprm_is_check boolean which can be set depending on how process_measurement is called. If the caller has a linux_binprm pointer and the function is BPRM_CHECK we can determine is_check and set it then. Otherwise set it to false. | ||||
| CVE-2026-46094 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: ext4: fix bounds check in check_xattrs() to prevent out-of-bounds access The bounds check for the next xattr entry in check_xattrs() uses (void *)next >= end, which allows next to point within sizeof(u32) bytes of end. On the next loop iteration, IS_LAST_ENTRY() reads 4 bytes via *(__u32 *)(entry), which can overrun the valid xattr region. For example, if next lands at end - 1, the check passes since next < end, but IS_LAST_ENTRY() reads 4 bytes starting at end - 1, accessing 3 bytes beyond the valid region. Fix this by changing the check to (void *)next + sizeof(u32) > end, ensuring there is always enough space for the IS_LAST_ENTRY() read on the subsequent iteration. | ||||
