CVE-2024-26739

In the Linux kernel, the following vulnerability has been resolved: net/sched: actmirred: don't override retval if we already lost the skb If we're redirecting the skb, and haven't called tcfmirredforward, yet, we need to tell the core to drop the skb by setting the retcode to SHOT. If we have...

CVE-2024-26739

CVE-2024-26739 affects the Linux kernel net/sched component (act_mirred) where overriding the skb return value after routing could lead to Use-After-Free if tcf_mirred_forward() had been called. The fix moves the retval override to the error path that actually requires it, preventing UaF when the...
