CVE-2026-31431
High · 7.8
KEV Urgent · 72 Public exploit CWE-669 Apr 22, 2026
Linux Kernel Incorrect Resource Transfer Between Spheres Vulnerability
In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - Revert to operating out-of-place
This mostly reverts commit 72548b093ee3 except for the copying of
the associated data.
There is no benefit in operating in-place in algif_aead since the
source and destination come from different mappings. Get rid of
all the complexity added for in-place operation and just copy the
AD directly.
CVE-2025-39964

KEV High · 55 Public exploit CWE-362 Oct 13, 2025
Linux Kernel Race Condition Vulnerability
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg
Issuing two writes to the same af_alg socket is bogus as the
data will be interleaved in an unpredictable fashion. Furthermore,
concurrent writes may create inconsistencies in the internal
socket state.
Disallow this by adding a new ctx->write field that indiciates
exclusive ownership for writing.
