SUSE CVE-2026-53233

In the Linux kernel, the following vulnerability has been resolved: netdev: fix double-free in netdevnlbindrxdoit Sashiko flags that genlmsgreply always consumes the skb. The error path calls nlmsgfreersp so we can't jump directly to it. Let's not unbind, just propagate the error to the user. Thi...

CVE-2026-52988

A flaw was found in the Linux kernel's netfilter component. This vulnerability involves a concurrency issue during updates to netfilter rulesets. When multiple updates occur simultaneously, improper synchronization could lead to unsafe data access during netlink dump list traversal. This could...

CVE-2026-53231

In the Linux kernel, the following vulnerability has been resolved: net: phy: don't try to setup PHY-driven SFP cages when using genphy We don't have support for PHY-driver SFP cages with the genphy code. On top of that, it was found by sashiko that running sfpbusaddupstream for genphy deadlocks,...

CVE-2026-53259

CVE-2026-53259 (Linux kernel) fixes a race in IPv6 anycast address management. The root cause was a window where inserting an aca into the global inet6_acaddr_lst[] and its hash could be separated from the teardown path (RTNL), causing the ac_addr to be freed while still linked, i.e., a slab-use-...

CVE-2026-53231

CVE-2026-53231 (Linux kernel) : The issue affects the PHY subsystem where PHY-driven SFP cages are not supported with the genphy code. Investigations show that sfp_bus_add_upstream() for genphy can deadlock because PHY probing runs under RTNL for genphy while non-genphy drivers do not. The root c...

PT-2026-52328

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A double-free issue exists in the netdev nl bind rx doit function. This occurs because genlmsg reply always consumes the socket buffer skb, but the error path incorrectly calls nlmsg...

PT-2026-52326

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the network PHY subsystem where the system attempts to set up PHY-driven SFP cages when using genphy. Because genphy does not support PHY-driver SFP cages, calling the...
