CVE-2021-47274

CVE-2021-47274 (Linux kernel tracing): The issue stems from a length check in tracing that can cause memory corruption in ftrace data, leading to kernel crashes. A fix was added (commit b220c049d519) to validate the length before exposing the trace buffer, addressing overflow introduced by a prio...

CVE-2024-26883

CVE-2024-26883 : In the Linux kernel, a vulnerability was fixed that affects 32-bit architectures in the stackmap handling used by BPF. The overflow risk arises when roundup_pow_of_two() is used to compute the number of hash buckets, as a 32‑bit left shift can overflow and cause undefined behavio...

CVE-2023-52933

CVE-2023-52933 affects the Linux kernel Squashfs xattr_ids handling. Two overflow flaws were exposed by a corrupted filesystem: on 64‑bit systems, sign extension of xattr_ids when multiplied by sizeof(struct squashfs_xattr_id) can overflow and yield an incorrect len; on 32‑bit systems, the unsign...
