Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: validate ltreedepth to avoid out-of-bounds access

The ltreedepth field is 16-bit (_le16), but the actual maximum depth is limited to OCFS2MAXPATHDEPTH.

Add a check to prevent out-of-bounds access if ltreedepth has an invalid value, which may occur when reading from a corrupted mounted disk [1].(CVE-2025-22079)

In the Linux kernel, the following vulnerability has been resolved:

mfd: ene-kb3930: Fix a potential NULL pointer dereference

The offgpios could be NULL. Add missing check in the kb3930probe(). This is similar to the issue fixed in commit b1ba8bcb2d1f ("backlight: hx8357: Fix potential NULL pointer dereference").

This was detected by our static analysis tool.(CVE-2025-23146)

In the Linux kernel, the following vulnerability has been resolved:

jbd2: remove wrong sb->s_sequence check

Journal emptiness is not determined by sb->ssequence == 0 but rather by sb->sstart == 0 (which is set a few lines above). Furthermore 0 is a valid transaction ID so the check can spuriously trigger. Remove the invalid WARN_ON.(CVE-2025-37839)

In the Linux kernel, bitputcsaligned()/unaligned() derived the glyph pointer from the character value masked by 0xff/0x1ff, which may exceed the actual font's glyph count and read past the end of the built-in font array. Clamp the index to the actual glyph count before computing the address. This fixes a global out-of-bounds read reported by syzbot.(CVE-2025-40322)
