UBUNTU-CVE-2026-97958

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsapi: Don't replay RTMGETCHAIN in tcctlchain. If a netlink socket sends RTMGETCHAIN requests repeatedly without recving the responses, tcctlchain hogs CPU and triggers Hung Task splat. 0 As caught in the stack trace,...

CVE-2026-98105 net: ethernet: oa_tc6: Improve the error recovery

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: oatc6: Improve the error recovery When oversubscribed traffic causes lot of buffer overflow errors, probably due to loss of data chunks, driver fails to find a data chunk with endvalid bit set, before it runs out o...

CVE-2026-98105

The Linux kernel contains a vulnerability in the oa_tc6 ethernet driver where oversubscribed traffic causing buffer overflow errors can lead to a kernel assert during skb_put. This occurs because the driver fails to identify a data chunk with the end_valid bit set before exhausting sk buffer spac...

CVE-2026-98104

The Linux kernel contains a vulnerability in the net/sched: cls_u32 component where the node ID pool can become exhausted. When the pool is full, gen_new_kid() fails to report an error and instead returns a maximum value, leading u32_change() to insert a duplicate handle into the hash table. Simi...
