Vulnerability from cvelistv5
Published

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - Set merge to zero early in af_alg_sendmsg If an error causes af_alg_sendmsg to abort, ctx->merge may contain a garbage value from the previous loop. This may then trigger a crash on the next entry into af_alg_sendmsg when it attempts to do a merge that can't be done. Fix this by setting ctx->merge to zero near the start of the loop.

Exploitation requires a local account to issue the syscalls.\nAC:L - The attacker controls both the error-aborting sendmsg (a fault in memcpy_from_msg or a forced allocation error is trivially induced) and the subsequent merge-triggering sendmsg, so the condition is reliably created; heap grooming for full exploitation is also within attacker control.\nPR:L - Creating and driving an AF_ALG socket requires no capabilities and passes no privilege check, so any basic unprivileged local user can reach the vulnerable path.\nUI:N - The entire sequence is performed by the attacker\u0027s own process with no victim action required.\nS:U - The corruption stays within the kernel\u0027s own security authority (standard local privilege escalation); no VM/IOMMU/sandbox boundary is crossed.\nC:H - The stale merge flag causes an out-of-bounds scatterlist read and a heap write primitive that can be leveraged to disclose kernel memory contents.\nI:H - The merge path performs an attacker-controlled write to an address derived from an out-of-bounds-read scatterlist entry, giving a heap out-of-bounds write suitable for control-flow hijacking/privilege escalation.\nA:H - The inconsistent tsgl state and wild write reliably cause kernel memory corruption and panic/oops."
