CVE-2026-46018

CVE-2026-46018 is a Linux kernel issue in ALSA: usb-audio (UAC2) where parse_uac2_sample_rate_range() capped at MAX_NR_RATES but only broke the inner loop; a malformed UAC2 RANGE could continue parsing and flood with "invalid uac2 rates". The fix stops the whole parse at the cap and returns the c...

CVE-2026-46002 ext2: reject inodes with zero i_nlink and valid mode in ext2_iget()

In the Linux kernel, the following vulnerability has been resolved: ext2: reject inodes with zero inlink and valid mode in ext2iget ext2iget already rejects inodes with inlink == 0 when imode is zero or idtime is set, treating them as deleted. However, the case of inlink == 0 with a non-zero mode...

CVE-2026-45984 gfs2: Fix use-after-free in iomap inline data write path

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix use-after-free in iomap inline data write path The inline data buffer head dibh is being released prematurely in gfs2iomapbegin via releasemetapath while iomap-inlinedata still points to dibh-bdata. This causes a...

In the Linux kernel, the following vulnerability has been resolved: staging: greybus: lights: avoid NULL deref gblightslightconfig stores channelcount before allocating the channels array. If kcalloc fails, gblightsrelease iterates the non-zero count and dereferences light-channels, which is NULL...

CVE-2026-45968 cpuidle: Skip governor when only one idle state is available

In the Linux kernel, the following vulnerability has been resolved: cpuidle: Skip governor when only one idle state is available On certain platforms PowerNV systems without a power-mgt DT node, cpuidle may register only a single idle state. In cases where that single state is a polling state sta...

CVE-2026-45941

CVE-2026-45941 concerns the Linux kernel tpm_i2c_infineon locality handling. The root cause is a timeout in get_burstcount() that can return -EBUSY and cause the function to exit without releasing the locality acquired earlier in tpm_tis_i2c_send(), risking resource exhaustion. The mitigation acr...
