CVE-2025-21780

CVE-2025-21780 affects the Linux kernel DRM/AMDGPU, where a local attacker could overflow a PPTABLE buffer in smu_sys_set_pp_table() by cycling pptables via sysfs. The issue arises when a small pptable is followed by a larger one, enabling a buffer overflow as described in the advisory. This vuln...

CVE-2025-21778

CVE-2025-21778 (Linux kernel) involves a crash when mmap() is used on a persistent tracing ring buffer that is attached to reserve_mem. The root cause is that the code maps ring buffer pages using virt_to_page() on memory that is vmap()’d, which is invalid for that memory type and can trigger a p...

CVE-2025-21775 can: ctucanfd: handle skb allocation failure

In the Linux kernel, the following vulnerability has been resolved: can: ctucanfd: handle skb allocation failure If skb allocation fails, the pointer to struct canframe is NULL. This is actually handled everywhere inside ctucanerrinterrupt except for the only place. Add the missed NULL check. Fou...

CVE-2025-21775

CVE-2025-21775 affects the Linux kernel CAN ctucanfd component. When skb allocation fails, the can_frame pointer can be NULL, and one NULL check was missed in ctucan_err_interrupt(); a fix adding the NULL check was implemented in the kernel (see references to the can: ctucanfd: handle skb allocat...

CVE-2025-21771

CVE-2025-21771 affects the Linux kernel sched_ext subsystem. It stems from incorrect autogroup migration detection in the cgroup/migration path where scx_move_task() could misclassify a non-root cgroup migration as autogroup root migration, triggering a warning. The fix changes the call path by a...

CVE-2025-21772

CVE-2025-21772 involves the Linux kernel partition probing path (mac partition handling). The fix addresses processing of bogus partition tables by: (1) using put_dev_sector() for the bailout when a bad partoffset occurs, after a successful read_part_sector(); (2) rejecting partition tables that ...

CVE-2025-21770

In the Linux kernel, the following vulnerability has been resolved: iommu: Fix potential memory leak in iopfqueueremovedevice The iopfqueueremovedevice helper removes a device from the per-iommu iopf queue when PRI is disabled on the device. It responds to all outstanding iopf's with an...

CVE-2025-21769

In the Linux kernel, the following vulnerability has been resolved: ptp: vmclock: Add .owner to vmclockmiscdevfops Without the .owner field, the module can be unloaded while /dev/vmclock0 is open, leading to an oops...

CVE-2025-21769

CVE-2025-21769 affects the Linux kernel: the vmclock misc device lacked the .owner field, allowing a module unload while /dev/vmclock0 is open and causing an oops. The fix adds the .owner field to vmclock_miscdev_fops to prevent unloading during access. Public references indicate the vulnerabilit...

CVE-2025-21765

CVE-2025-21765 is a Linux kernel IPv6 stack issue where ip6_default_advmss() reads the net structure without proper RCU protection, risking use-after-free scenarios. The vulnerability is fixed in updated kernels across Linux distributions (examples: ALAS2KERNEL advisories for AL2 kernels 5.10/5.1...

CVE-2025-21766

CVE-2025-21766 concerns the Linux kernel IPv4 path. The issue is in __ip_rt_update_pmtu(), which must use Read-Copy-Update (RCU) protection to ensure the net structure it reads cannot disappear during updates.
