In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Delay put pmc->idev in mld_del_delrec() pmc->idev is still used in ip6_mc_clear_src(), so as mld_clear_delrec() does, the reference should be put after ip6_mc_clear_src()…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
