Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: ima: fix out-of-bounds read in
xattr_verify() The digest-length check in xattr_verify() mixes int and size_t: if (xattr_len -
sizeof(xattr_value->type) - hash_start >= iint->ima_hash->length) sizeof() yields size_t, so the usual
arithmetic conversions promote the whole left-hand side to unsigned 64-bit before the subtraction runs.
For a truncated xattr this underflows instead of going negative: a 1-byte IMA_XATTR_DIGEST_NG xattr
(xattr_len == 1, hash_start == 1) turns "1 - 1 - 1" into SIZE_MAX, which is trivially >= ima_hash->length.
The check then passes and the following memcmp() reads iint->ima_hash->length bytes starting past the end
of the buffer vfs_getxattr_alloc() allocated for it. Nothing upstream clamps xattr_len back into a safe
range first: ima_get_hash_algo() only special-cases xattr_len < 2 to pick a default algorithm, and
evm_verifyxattr() returns INTEGRITY_UNKNOWN rather than failing when no HMAC key is loaded, so a truncated
security.ima value reaches the length check as-is. Rewrite the comparison so every operand stays a signed
int and no implicit conversion to size_t can occur. (CVE-2026-74671)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
