CVE-2026-99030

The Linux kernel contains a vulnerability in the skb_copy_and_csum_bits() function where unreadable fragments cause the function to return 0 after only copying the linear part. This leaves stale bytes in the caller's buffer, which is then sent over the wire as part of an ICMP error quote or a dri...

CVE-2026-99029 net: sparx5: free the matchall entry on destroy

In the Linux kernel, the following vulnerability has been resolved: net: sparx5: free the matchall entry on destroy sparx5tcmatchallreplace allocates a struct sparx5mallentry for every offloaded matchall filter and adds it to sparx5-mallentries. sparx5tcmatchalldestroy removes the entry from the...

CVE-2026-99029

The Linux kernel contains a memory leak vulnerability in the sparx5 network driver. Specifically, the function sparx5_tc_matchall_replace() allocates a struct sparx5_mall_entry for offloaded matchall filters, but sparx5_tc_matchall_destroy() removes these entries from the list without freeing the...

CVE-2026-99028

The Linux kernel contains a vulnerability in the xilinx axienet driver where outstanding DMA buffers are leaked during dmaengine_stop. Specifically, dmaengine_terminate_sync() aborts descriptors without executing completion callbacks, causing the driver to free only the ring shells while leaking ...

CVE-2026-99027 net: team: stop reusing skb after queue override

In the Linux kernel, the following vulnerability has been resolved: net: team: stop reusing skb after queue override A nonzero devqueuexmit result does not return ownership of the skb. When an override port's qdisc drops it, the queue override helper used to try another port or the mode transmit ...

CVE-2026-99027

The Linux kernel contains a slab-use-after-free vulnerability within the net: team component. The issue occurs because a nonzero dev_queue_xmit() result does not return ownership of the skb . Consequently, when an override port's qdisc drops the packet, the queue override helper incorrectly attem...

CVE-2026-99026 net: team: free skb when broadcast has no txable port

In the Linux kernel, the following vulnerability has been resolved: net: team: free skb when broadcast has no txable port bctransmit sends the original skb through the last txable port. When no port is txable, it returns false without consuming the skb, but teamxmit still returns NETDEVTXOK...

CVE-2026-99026

The Linux kernel contains a memory management issue in the net: team component. Specifically, when a broadcast transmission has no txable port, the bc_transmit() function returns false without consuming the original skb , yet team_xmit() returns NETDEV_TX_OK. This causes AF_PACKET sends to retain...
