UBUNTU-CVE-2025-40295

In the Linux kernel, the following vulnerability has been resolved: fscrypt: fix left shift underflow when inode-iblkbits PAGESHIFT When simulating an nvme device on qemu with both logicalblocksize and physicalblocksize set to 8 KiB, an error trace appears during partition table reading at boot...

CVE-2025-40295 fscrypt: fix left shift underflow when inode->i_blkbits > PAGE_SHIFT

In the Linux kernel, the following vulnerability has been resolved: fscrypt: fix left shift underflow when inode-iblkbits PAGESHIFT When simulating an nvme device on qemu with both logicalblocksize and physicalblocksize set to 8 KiB, an error trace appears during partition table reading at boot...

CVE-2025-40295

CVE-2025-40295 corresponds to a Linux kernel issue where an underflow in a left shift can occur in fscrypt when inode->i_blkbits exceeds PAGE_SHIFT (e.g., with 8 KiB block sizes under TRANSPARENT_HUGEPAGE). The evidence shows a UBSAN shift-out-of-bounds warning during block device reads, trace...

PT-2025-49428

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.18.0-rc2+ Description The Linux kernel contains an issue within the fscrypt component where a left shift underflow can occur when inode-i blkbits is greater than PAGE SHIFT. This can happen when simulating an...

UBUNTU-CVE-2024-50211

In the Linux kernel, the following vulnerability has been resolved: udf: refactor inodebmap to handle error Refactor inodebmap to handle error since udfnextaext can return error now. On situations like ftruncate, udfextendfile can now detect errors and bail out early without resorting to checking...
