The CVE is addressed by adding siz...

CVE-2026-43223

CVE-2026-43223 concerns the Linux kernel media driver pvrusb2. The issue arises when pvr2_send_request_ex() submits a write URB and, if the subsequent read URB submission fails (e.g., due to -ENOMEM), returns early without waiting for the write to complete. Because the same URB structure is reuse...

CVE-2026-43225

CVE-2026-43225 involves a memory leak in the Linux kernel RTL8723BS staging path. Specifically, cfg80211_inform_bss_frame() may return NULL on a failure path, and the allocated buffer buf was not freed before an early return. This could leak memory. The issue is resolved by ensuring buf is freed ...

CVE-2026-53023 in the Linux kernel affects the ntfs3 filesystem driver: when converting on-disk volume labels from UTF-16 to UTF-8, the cached label in sbi->volume.label is not guaranteed to be NUL-terminated, which could lead to reading past the buffer in ntfs3_label_show(). The fix explicitl...

CVE-2026-53024

Summary: CVE-2026-53024 affects the Linux kernel Greybus raw subsystem. A use-after-free can occur when a user writes to a chardev after disconnect, because gb_connection_destroy frees the connection object during disconnect and a subsequent write may access that freed object, potentially trigger...

CVE-2026-53101

CVE-2026-53101 is a Linux kernel issue affecting the wifi mt76/mt7921 path. The root cause is a potential mutex deadlock between mt7921_roc_abort_sync and roc_work: roc_work() holds dev->mt76.mutex while cancel_work_sync() waits for roc_work() to finish. If the caller already owns the mutex, b...

CVE-2026-53124

CVE-2026-53124 concerns the Linux kernel ublk subsystem. A per-IO canceled flag incorrectly remains set if a ublk server dies during device recovery before all IOs are fetched, causing cancellation of fetch commands to potentially never complete. This leaves outstanding I/O and can lead to resour...

CVE-2026-53141

The CVE-2026-53141 issue affects the Linux kernel drm/v3d driver’s global performance monitor reference counting.
