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...

CVE-2026-98104 net/sched: cls_u32: fix duplicate handle when node ID pool is exhausted

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsu32: fix duplicate handle when node ID pool is exhausted gennewkid falls back to returning max htid | 0xFFF when both idrallocu32 ranges are full, instead of reporting an error. u32change trusts that value and inser...

CVE-2026-98087

The Linux kernel contains a vulnerability where the RT balancer enters a retry loop when handling migrate_disable() 'd Real-Time (RT) tasks. Because these tasks remain on the pushable list while being pinned, the scheduler repeatedly attempts to push them, fails, and falls back to pushing the cur...
