CVE-2026-98117

The Linux kernel contains a vulnerability in the cachefiles component where the trace_cachefiles_coherency() function incorrectly handles coherency data in struct cachefiles_xattr. Specifically, it passes a pointer to a __be64 over data of variable length (which could be 0 bytes), potentially lea...

EUVD-2026-86948

In the Linux kernel, the following vulnerability has been resolved: cachefiles: Fix potential UAF/KASAN warning Currently, tracecachefilescoherency is being passed a pointer to a be64 lain over the coherency data in struct cachefilesxattr so that it can display the first 8 bytes. However, the dat...

CVE-2026-98116

The Linux kernel contains a page-level use-after-free vulnerability in the ALSA component. The issue arises because the PCM stream lock is released before the buffer is actually freed during reallocation, while snd_pcm_mmap_data() lacks any locking. This allows a concurrent mmap() call to slip in...

CVE-2026-98116 ALSA: pcm: Serialize PCM mmap with buffer reallocation to fix page UAF

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Serialize PCM mmap with buffer reallocation to fix page UAF sndpcmhwparams and sndpcmhwfree guard buffer reallocation with an mmapcount check performed under the PCM stream lock, but the lock is released long before th...

CVE-2026-98115

The Linux kernel contains a vulnerability in ksmbd regarding the handling of SMB3 multichannel requests. The issue arises because shared session objects may be freed before all bound channels are processed. Additionally, a deferred byte-range lock can remain counted as a running request, waking o...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: safely drain sessions during logoff SMB3 multichannel allows requests for one session to run on multiple connections. Wait for all channels bound to a session before freeing shared session objects. A deferred byte-range lo...

CVE-2026-98114

The Linux kernel 's ksmbd component is vulnerable to an issue where the parse_dacl() function silently accepts truncated ACEs and allocation failures. This allows set_info_sec() to proceed with an incomplete ACL conversion, potentially leading to incorrect permission handling. The fix involves re...

CVE-2026-98112

The Linux kernel contains a vulnerability in ksmbd related to the listener task lifetime during network device events. The issue occurs because the netdevice notifier shuts down the listening socket before calling kthread_stop(), potentially allowing the task_struct to be freed before kthread_sto...

CVE-2026-98113

In the Linux kernel, the following vulnerability has been resolved: ksmbd: rate limit unmapped SID errors A client can include many structurally valid but unmapped SIDs in a DACL. Logging every mapping failure lets one request generate hundreds of kernel error messages. Rate limit the message to...

EUVD-2026-86943

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix listener task lifetime on netdev events The listener thread exits when its listening socket is shutdown. The netdevice notifier shuts down the socket before calling kthreadstop, so the taskstruct can be freed before...

CVE-2026-98111

The Linux kernel contains a vulnerability in the btintel Bluetooth driver within the btintel_parse_version_tlv() function. The flaw occurs because the function verifies the presence of a TLV (Type-Length-Value) but fails to ensure the value length is sufficient for the specific TLV type. This ove...
