GHSA-2274-3HGR-WXV6
Vulnerability from github – Published: 2026-04-22 09:31 – Updated: 2026-05-18 18:31
VLAI
Details
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.
Severity
7.8 (High)
