CVE-2026-63912

The CVE concerns the Linux kernel XFRM/ESP path. The vulnerability arises in the ESP out-of-place fast path where an out-of-line trailer is written before dest page frag allocation; the head gate and tail code previously treated skb->data_len and tailen separately, risking an overflow when the...

CVE-2026-63838

The CVE-2026-63838 entry concerns the Linux kernel ASoC rsnd subsystem. It fixes a potential out-of-bounds access in rsnd_dai_of_node() caused by a boundary check (i >= RSND_MAX_COMPONENT) not guaranteeing component_dais[RSND_MAX_COMPONENT] remains zero, so a loop could read past the end of th...

CVE-2026-63838 ASoC: rsnd: Fix potential out-of-bounds access of component_dais[]

In the Linux kernel, the following vulnerability has been resolved: ASoC: rsnd: Fix potential out-of-bounds access of componentdais componentdaisRSNDMAXCOMPONENT is initially zero-initialized and later populated in rsnddaiofnode. However, the existing boundary check: if i = RSNDMAXCOMPONENT does...

CVE-2026-63833

The CVE-2026-63833 issue affects the Linux kernel ntfs3 module: an unprivileged user on a writable NTFS3 mount could abuse the empty-prefix xattr handler to write to reserved $LX* attributes, enabling planting root ownership and S_ISUID on their file and obtaining effective user ID 0 after inode ...

CVE-2026-63833 ntfs3: reject direct userspace writes to reserved $LX* xattrs

In the Linux kernel, the following vulnerability has been resolved: ntfs3: reject direct userspace writes to reserved $LX xattrs NTFS3 uses $LXUID, $LXGID, $LXMOD and $LXDEV as internal WSL permission metadata and reloads them into iuid, igid and imode from ntfsgetwslperm. Because the empty-prefi...

CVE-2026-63809

CVE-2026-63809 affects the Linux kernel memory-management path used by BPF when handling proc sysctl writes. The vulnerability stems from proc_sys_call_handler() allocating a temporary sysctl buffer with kvzalloc() and passing it to __cgroup_bpf_run_filter_sysctl(); since kvzalloc() may fall back...

CVE-2026-53379 media: i2c: ov8856: free control handler on error in ov8856_init_controls()

In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov8856: free control handler on error in ov8856initcontrols The control handler wasn't freed if adding controls failed, add an error exit label and convert the existing error return to use it...

CVE-2026-53379

The CVE affects the Linux kernel media/i2c ov8856 driver. In ov8856_init_controls(), the control handler is not freed if adding controls fails, leading to a resource leak on the error path.
