AI-suggested

A security update is available from Red Hat and SUSE. Systems running affected kernel versions should apply the vendor-provided patches and reboot to activate the fix. Refer to the Red Hat advisory RHSA-2025:15740 and SUSE security updates for detailed instructions.

Description

A moderate severity vulnerability in the Linux kernel related to IPv6 multicast handling has been resolved. The issue involves the timing of releasing a reference to pmc->idev in the mld_del_delrec() function, which could lead to use of a freed reference in ip6_mc_clear_src(). This flaw affects various Red Hat Enterprise Linux 9 kernel packages and SUSE kernel versions. A security update is available and should be applied with a system reboot.
