CVE-2026-31431
crypto: algif_aead - Revert to operating out-of-place
Was es ist
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.
CISA: Linux Kernel contains an incorrect resource transfer between spheres vulnerability that could allow for privilege escalation.
Was zu tun ist
"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
