CVE-2026-98805 tipc: prevent GCM nonce reuse on peer key changes

In the Linux kernel, the following vulnerability has been resolved: tipc: prevent GCM nonce reuse on peer key changes TIPC can encrypt traffic between nodes using a different transmit key for each node. In this mode, the AES-GCM nonce for a packet sent to a known peer consists of a 32-bit prefix ...

CVE-2026-98804 net: page_pool: fix use-after-free in page_pool_recycle_ring_bulk()

In the Linux kernel, the following vulnerability has been resolved: net: pagepool: fix use-after-free in pagepoolrecycleringbulk With CONFIGPAGEPOOLSTATS=y, pagepoolrecycleringbulk updates the recycle stats after dropping the producer lock.

CVE-2026-98804

The Linux kernel contains a use-after-free vulnerability in the net: page_pool component when CONFIG_PAGE_POOL_STATS=y is enabled. The root cause is that page_pool_recycle_ring_bulk() updates recycle statistics after dropping the producer lock. This allows page_pool_release() to pass its producer...

CVE-2026-98803 net: stmmac: fix rx Scatter-Gather support

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix rx Scatter-Gather support When a received frame is larger than dmabufsz, the DMA scatters it across multiple RX descriptors rx Scatter-Gather. The secondary RX buffer secpage was only allocated and programmed whe...

CVE-2026-98803

The Linux kernel contains a vulnerability in the stmmac driver where received frames larger than dma_buf_sz were not correctly handled for regular frames lacking split-header (SPH) active. Specifically, the secondary RX buffer (buffer2 ) was neither allocated nor mapped, causing the DMA to write ...

CVE-2026-98802

A vulnerability exists in the Linux kernel where the functions advance_nextseg() and seg6_next_csid_advance_arg() modify the SRH Segments Left field and the IPv6 destination address without first verifying if the packet data is writable. This issue occurs because the socket buffer (skb) may be sh...

CVE-2026-98801

The Linux kernel contained a vulnerability where the SO_RESERVE_MEM socket option was improperly handled for UDP sockets . Because the kernel only checked for account ownership rather than protocol type, concurrent UDP packet reception and memory reservation calls could cause race conditions , le...

In the Linux kernel, the following vulnerability has been resolved: bpf: Wait for an RCU tasks grace period before freeing trampoline progs When a prog is detached from a trampoline, it is freed after an RCU grace period, or an RCU tasks trace one if it is sleepable. This covers the tasks that ar...

CVE-2026-98800

The Linux kernel contains a vulnerability where programs linked to a trampoline can be freed prematurely when detached. Specifically, on a preemptible kernel , a task preempted in the trampoline just before the enter helper may call the program after it has been freed, leading to a vmalloc-out-of...
