Description
A use-after-free issue has been identified in the Linux kernel, specifically in the block, bfq component. The issue arises when
bic->bfqq is accessed in bic set bfqq(), but bic->bfqq is freed in certain contexts before bic set bfqq() is called. This problem is resolved by ensuring that bfqq is always freed after bic set bfqq().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
