PT-2024-36892

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.74 Description A vulnerability in the Linux kernel has been resolved, specifically related to the LoongArch architecture and PREEMPT RT kernels. The issue arises from the replacement of normal spinlocks with ...

kernel: rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic()

A locking violation was found in the Linux kernel RCU-tasks subsystem's callback list initialization. During system boot, the initialization code calls prinfo while holding the rtp-cbsgbllock spinlock, causing a potentially sleeping function to be called in atomic context, which results in kernel...

kernel: tty: n_gsm: avoid call of sleeping functions from atomic context

CVE-2024-50067 uprobe: avoid out-of-bounds memory access of fetching args

In the Linux kernel, the following vulnerability has been resolved: uprobe: avoid out-of-bounds memory access of fetching args Uprobe needs to fetch args into a percpu buffer, and then copy to ring buffer to avoid non-atomic context problem. Sometimes user-space strings, arrays can be very large,...

CVE-2024-50067

CVE-2024-50067 relates to the Linux kernel, where a vulnerability in upstream probing (uprobe) could cause an out-of-bounds memory access when fetching arguments for tracing. The issue arises because data may be larger than the per-CPU buffer size (a page), and store_trace_args() may not detect d...

SUSE CVE-2024-46867

In the Linux kernel, the following vulnerability has been resolved: drm/xe/client: fix deadlock in showmeminfo There is a real deadlock as well as sleeping in atomic bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix...

kernel: isdn: mISDN: Fix sleeping function called from invalid context

In the Linux kernel, the following vulnerability has been resolved: isdn: mISDN: Fix sleeping function called from invalid context The driver can call card-isac.release function from an atomic context. Fix this by calling this function after releasing the lock. The following log reveals it:...

CVE-2024-46691

CVE-2024-46691 affects the Linux kernel USB Type-C UCSI path. The unregister path (ucsi_unregister) moved to be called from atomic context due to a PMIC_GLINK/IRq-callback spinlock change, making sleepable code paths (unregister) unsafe. This creates a potential flaw where unregistration can occu...
