CVE-2024-57982

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been identified, related to an out-of-bounds read during lookup in the xfrm state. The issue arises when lookup and resize operations run in parallel, and the hash functions can observe a hmask value that is too large for the new hlist array. This is due to the xfrm state hash generation seqlock ensuring a retry, but not preventing the hash functions from accessing an inconsistent hmask value. The vulnerability can be exploited when the update to state bydst is not properly synchronized with the lookup function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
