kernel: scsi: lpfc: Fix buffer free/clear order in deferred receive path

A use-after-free vulnerability exists in the linux kernel such that the buffer release sequence in the deferred receive path. The code freed the RQ buffer first and only then cleared the context pointer under the lock...

SUSE CVE-2025-68321

In the Linux kernel, the following vulnerability has been resolved: pagepool: always add GFPNOWARN for ATOMIC allocations Driver authors often forget to add GFPNOWARN for page allocation from the datapath. This is annoying to users as OOMs are a fact of life, and we pretty much expect network Rx ...

EUVD-2025-203776

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: lookup hciconn on RX path on protocol side The hdev lock/lookup/unlock/use pattern in the packet RX path doesn't ensure hciconn is not concurrently modified/deleted. This locking appears to be leftover from...

EUVD-2025-203779

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: fix fragment overflow handling in RX path The atlantic driver can receive packets with more than MAXSKBFRAGS 17 fragments when handling large multi-descriptor packets. This causes an out-of-bounds write in...

CVE-2025-68302

In the Linux kernel, the following vulnerability has been resolved: net: sxgbe: fix potential NULL dereference in sxgberx Currently, when skb is null, the driver prints an error and then dereferences skb on the next line. To fix this, let's add a 'break' after the error message to switch to...

CVE-2025-68301

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: fix fragment overflow handling in RX path The atlantic driver can receive packets with more than MAXSKBFRAGS 17 fragments when handling large multi-descriptor packets. This causes an out-of-bounds write in...

CVE-2025-68304

AZL-74172 CVE-2025-68291 affecting package kernel for versions less than 6.6.121.1-1

In the Linux kernel, the following vulnerability has been resolved: mptcp: Initialise rcvmss before calling tcpsendactivereset in mptcpdofastclose. syzbot reported divide-by-zero in tcpselectwindow by MPTCP socket. 0 We had a similar issue for the bare TCP and fixed in commit 499350a5a6e7 "tcp:...

CVE-2025-68301

The CVE-2025-68301 issue affects the Linux kernel atlantic driver (AQC113 10G NIC) where the RX path could overflow fragments when a packet requires more than MAX_SKB_FRAGS, causing an out-of-bounds write in skb_add_rx_frag_netmem() and a kernel panic. The fix adds an assumption of an extra fragm...

CVE-2025-68301 net: atlantic: fix fragment overflow handling in RX path

CVE-2025-68291

The CVE-2025-68291 issue affects the Linux kernel MPTCP path: in mptcp_do_fastclose(), rcv_mss was not initialised before triggering tcp_send_active_reset(), leading to a divide-by-zero in __tcp_select_window() for MPTCP sockets. The fix mirrors a prior bare-TCP patch by initialising rcv_mss (to ...

CVE-2025-68291 mptcp: Initialise rcv_mss before calling tcp_send_active_reset() in mptcp_do_fastclose().

In the Linux kernel, the following vulnerability has been resolved: mptcp: Initialise rcvmss before calling tcpsendactivereset in mptcpdofastclose. syzbot reported divide-by-zero in tcpselectwindow by MPTCP socket. 0 We had a similar issue for the bare TCP and fixed in commit 499350a5a6e7 "tcp:...

CVE-2025-40350

CVE-2025-40350 (net/mlx5e) is fixed in the Linux kernel for XDP multi-buffer handling. The mlx5 driver previously assumed an unchanged xdp_buff layout when XDP programs resize data, causing erroneous skb generation or kernel warnings. The fix records the original fragment count, rewinds the end f...

CVE-2025-40350 net/mlx5e: RX, Fix generating skb from non-linear xdp_buff for striding RQ

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: RX, Fix generating skb from non-linear xdpbuff for striding RQ XDP programs can change the layout of an xdpbuff through bpfxdpadjusttail and bpfxdpadjusthead. Therefore, the driver cannot assume the size of the linear...
