CVE-2024-44968

The connected Nessus entry for CVE-2024-44968 confirms a Linux kernel tick/broadcast timer regression where per-CPU pointer access was taken in a preemptible region due to compiler behavior. The fix moves the per-CPU pointer retrieval to the actual usage site, which is in a non-preemptible region...

CVE-2024-44968 tick/broadcast: Move per CPU pointer access into the atomic section

In the Linux kernel, the following vulnerability has been resolved: tick/broadcast: Move per CPU pointer access into the atomic section The recent fix for making the take over of the broadcast timer more reliable retrieves a per CPU pointer in preemptible context. This went unnoticed as compilers...

CVE-2024-44967 drm/mgag200: Bind I2C lifetime to DRM device

In the Linux kernel, the following vulnerability has been resolved: drm/mgag200: Bind I2C lifetime to DRM device Managed cleanup with devmaddactionorreset will release the I2C adapter when the underlying Linux device goes away. But the connector still refers to it, so this cleanup leaves behind a...

CVE-2024-44966 binfmt_flat: Fix corruption when not offsetting data start

In the Linux kernel, the following vulnerability has been resolved: binfmtflat: Fix corruption when not offsetting data start Commit 04d82a6d0881 "binfmtflat: allow not offsetting data start" introduced a RISC-V specific variant of the FLAT format which does not allocate any space for the obsolet...

CVE-2024-44966

CVE-2024-44966 is a Linux kernel vulnerability involving the binfmt_flat helper. A RISC-V specific FLAT format variant reserved no space for the obsolete shared library pointer array, but initialization code was not disabled, causing corruption of sizeof(long) bytes before the DATA segment (end o...

CVE-2024-44963

CVE-2024-44963 — Linux kernel (btrfs): The issue occurs in btrfs_free_tree_block() when freeing a tree block and an error occurs creating a delayed reference. Instead of handling the error, a BUG_ON() could trigger, causing space leakage if memory allocation fails or other errors propagate via bt...

CVE-2024-44962 Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading When unload the btnxpuart driver, its associated timer will be deleted. If the timer happens to be modified at this moment, it leads to the kernel ca...

CVE-2024-44961 drm/amdgpu: Forward soft recovery errors to userspace

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Forward soft recovery errors to userspace As we discussed before1, soft recovery should be forwarded to userspace, or we can get into a really bad state where apps will keep submitting hanging command buffers cascadin...

CVE-2024-44960 usb: gadget: core: Check for unset descriptor

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: core: Check for unset descriptor Make sure the descriptor has been set before looking at maxpacket. This fixes a null pointer panic in this case. This may happen if the gadget doesn't properly set up the endpoint for...

CVE-2024-44956 drm/xe/preempt_fence: enlarge the fence critical section

In the Linux kernel, the following vulnerability has been resolved: drm/xe/preemptfence: enlarge the fence critical section It is really easy to introduce subtle deadlocks in preemptfenceworkfunc since we operate on single global ordered-wq for signalling our preempt fences behind the scenes, so...

CVE-2024-44957 xen: privcmd: Switch from mutex to spinlock for irqfds

In the Linux kernel, the following vulnerability has been resolved: xen: privcmd: Switch from mutex to spinlock for irqfds irqfdwakeup gets EPOLLHUP, when it is called by eventfdrelease by way of wakeuppoll&ctx-wqh, EPOLLHUP, which gets called under spinlockirqsave. We can't use a mutex here as i...

CVE-2024-44954

CVE-2024-44954 concerns a race in the Linux kernel ALSA subsystem: concurrent access to the line6 midibuf from URB completion callbacks and rawmidi API can trigger a KMSAN warning. The root cause is a data race on midibuf usage; Linux kernel patch added a spinlock to protect the midibuf call path...

CVE-2024-44954

In the Linux kernel, the following vulnerability has been resolved: ALSA: line6: Fix racy access to midibuf There can be concurrent accesses to line6 midibuf from both the URB completion callback and the rawmidi API access. This could be a cause of KMSAN warning triggered by syzkaller below so pu...
