CVE-2024-35874
CVSS v2.0
7.5
High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a null pointer dereference in the
aio complete() function. Specifically, list del init careful() needs to be the last access to the wait queue entry, as it effectively unlocks access. Previously, finish wait() would see the empty list head and skip taking the lock, and then return, but the completion path would still attempt to do the wakeup after the task struct pointer had been overwritten.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
