In the Linux kernel, the following vulnerability has been resolved: net: thunderx: fix PTP device ref leak in nicvfprobe caviumptpget acquires a reference to the PTP PCI device through pcigetdevice. If any initialization step fails after caviumptpget, the PTP PCI device reference is leaked. Add a...

CVE-2026-98942

The Linux kernel contains a vulnerability in the sched_ext component where cid tables were visible to cid kfuncs while being modified. Specifically, the first enable published global pointers before they were filled, and subsequent operations overrode them in place. This allowed a racing TRACING ...

CVE-2026-98941 ext4: don't enable large folios on encrypted inodes

In the Linux kernel, the following vulnerability has been resolved: ext4: don't enable large folios on encrypted inodes Commit 709f0f1f1bf5 "ext4: add checks for large folio incompatibilities when BS PS" disables large folios at mount time if the "encrypt" feature is set. However, enabling that...

CVE-2026-98941

The Linux kernel is vulnerable in versions v6.19 through v7.2 due to an issue where the ext4 filesystem may enable large folios on encrypted inodes if the encryption feature is enabled while the filesystem is already mounted. This bypasses mount-time checks and causes a kernel NULL pointer derefe...

CVE-2026-98940

The Linux kernel contains a vulnerability in the ASoC: qcom: lpass-cpu driver where the system incorrectly uses a DAI ID (a hardware port ID) as an index for the variant->dai_driver table. Because DAI IDs may be sparse, this mismatch can cause the code to write beyond the table boundaries when...

CVE-2026-98939

The Linux kernel contains a vulnerability where a possible deadlock occurs on systems with a discrete GPU . The root cause is an x86 commit that introduced an mmap_read_lock() in kernel page protection munging code. This creates a circular locking dependency because the huge vmap code holds the s...

CVE-2026-98939 x86/mm: Drop unnecessary PMD page copy when freeing

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Drop unnecessary PMD page copy when freeing On a box with a discrete GPU, lockdep reports a possible deadlock as soon as kswapd shrinks the TTM page pool. The immediate cause is an x86 commit that added an mmapreadlock to...

CVE-2026-98938

The Linux kernel contains a vulnerability within the Rust implementation of IRQ handling. Specifically, because Devres::new() returns a Result by value (introduced in commit ba268514ea14), the registration.inner field remains uninitialized when request_irq() is called. This allows the IRQ callbac...
