Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved, related to the net sched component. The issue arises from the
cp->alloc hash not being updated after hash allocation in tcindex alloc perfect hash(), potentially leading to an out-of-bounds access. This was caused by a change in commit 599be01ee567, where the cp->hash calculation was moved before the first tcindex alloc perfect hash() call, but cp->alloc hash was left unchanged.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
