In the Linux kernel, the following vulnerability has been resolved: arm64: percpu: Fix LSE operations on 8,16-bit types The assembly for percpunamecasesz and percpunamereturncasesz doesn't use the 'sfx' macro argument to form the LSE instruction. Without 'sfx', a W register argument will imply a...

CVE-2026-98246

A use-after-free vulnerability exists in the Linux kernel Bluetooth stack within the hci_sync component. The hci_dev_close_sync() function clears the hdev->local_codecs list after releasing the hdev->lock, whereas additions and traversals in sco_sock_getsockopt() correctly acquire this lock...

EUVD-2026-93174

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Serialize local codec list cleanup hcidevclosesync clears hdev-localcodecs after releasing hdev-lock. Codec list additions and both traversals in scosockgetsockopt use that lock, but the close path does not. A...

In the Linux kernel, the following vulnerability has been resolved: btrfs: clear free space tree creation state on rebuild failure btrfsrebuildfreespacetree sets BTRFSFSCREATINGFREESPACETREE before rebuilding the free space tree. Several error paths return without clearing this flag. The...

CVE-2026-98245

The Linux kernel contains a vulnerability in the btrfs filesystem. The function mark_block_group_to_copy() iterates over the commit root while skip_locking is set to true. This allows a concurrent transaction commit to swap and free the commit root during iteration, resulting in a use-after-free ...

In the Linux kernel, the following vulnerability has been resolved: btrfs: take commit root semaphore when iterating in markblockgrouptocopy markblockgrouptocopy iterates over the commit root with skiplocking=true. A concurrent transaction commit can swap and free the commit root during iteration...

CVE-2026-98244

The Linux kernel btrfs filesystem contains a vulnerability where the btrfs_rebuild_free_space_tree() function fails to clear the BTRFS_FS_CREATING_FREE_SPACE_TREE flag on certain error paths. Specifically, a transaction restart failure can leave this flag set on a live filesystem, which results i...

CVE-2026-98243 dma-buf/dma-fence: fix checking signaling bit for timeline and driver name v3

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-fence: fix checking signaling bit for timeline and driver name v3 The patch "dma-buf: dma-fence: Fix potential NULL pointer dereference" changed the check to test for the ops pointer instead of the signaled bit to avo...

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-fence: fix checking signaling bit for timeline and driver name v3 The patch "dma-buf: dma-fence: Fix potential NULL pointer dereference" changed the check to test for the ops pointer instead of the signaled bit to avo...

CVE-2026-98243

A vulnerability exists in the Linux kernel 's dma-buf/dma-fence component. A previous patch intended to prevent a NULL pointer dereference by testing the ops pointer instead of the signaled bit inadvertently removed RCU protection for many dma_fence implementations. This loss of protection can le...

EUVD-2026-93170

In the Linux kernel, the following vulnerability has been resolved: dma-buf: Fix silent overflow for phys vec to sgt In case MMIO size is bigger than 4G and peer2peer DMA goes through host bridge, we trigger a code path that assigns the total linked IOVA which is greater than 4G to mappedlen...

CVE-2026-98242

A vulnerability in the Linux kernel dma-buf subsystem allows for a silent overflow when the MMIO size exceeds 4G during peer-to-peer DMA through a host bridge. The root cause is that mapped_len was declared as a 32-bit unsigned int, causing a wrap-around when accumulating size_t lengths. This tru...

CVE-2026-98240

The Linux kernel contains a vulnerability in the net: ip_tunnel component where options_len is used to calculate an option pointer before being initialized. This oversight leads to a buffer overflow during a memcpy operation, specifically when processing geneve_opts . This issue can trigger a ker...

CVE-2026-98241

The Linux kernel is vulnerable to an out-of-bounds read in the ipv6: xfrm component. The functions xfrm6_local_rxpmtu() and xfrm6_local_error() incorrectly assume that skb->sk always points to a full IPv6 socket. In scenarios where TCP SYN-ACK packets are owned by a TCP_NEW_SYN_RECV request_so...

CVE-2026-98241 ipv6: xfrm: use full sockets in local error paths

In the Linux kernel, the following vulnerability has been resolved: ipv6: xfrm: use full sockets in local error paths xfrm6localrxpmtu and xfrm6localerror dereference skb-sk as if it always pointed at a full IPv6 socket. That is not guaranteed. TCP SYN-ACK skbs can be owned by a TCPNEWSYNRECV...

In the Linux kernel, the following vulnerability has been resolved: net: lan743x: fix RX checksum use-after-free lan743xrxprocessbuffer adds each non-first receive buffer to the head skb's fraglist. On the last descriptor, lan743xrxtrimskb linearizes the head and frees the fragment skb metadata...

CVE-2026-98239

The Linux kernel contains a use-after-free vulnerability in the lan743x network driver. The issue occurs in lan743x_rx_process_buffer() when a packet spans multiple receive buffers; specifically, lan743x_rx_trim_skb() frees fragment skb metadata on the last descriptor, but the checksum-success pa...
