CVE-2024-55881 – KVM: x86: Play nice with protected guests in complete_hypercall_exit()
https://notcve.org/view.php?id=CVE-2024-55881
11 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Play nice with protected guests in complete_hypercall_exit() Use is_64_bit_hypercall() instead of is_64_bit_mode() to detect a 64-bit hypercall when completing said hypercall. For guests with protected state, e.g. SEV-ES and SEV-SNP, KVM must assume the hypercall was made in 64-bit mode as the vCPU state needed to detect 64-bit mode is unavailable. Hacking the sev_smoke_test selftest to generate a KVM_HC_MAP_GPA_RANGE hypercall vi... • https://git.kernel.org/stable/c/5969e2435cbd7f0ce8c28d717bfc39987ee8d8f1 •
CVE-2024-53690 – nilfs2: prevent use of deleted inode

11 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: nilfs2: prevent use of deleted inode syzbot reported a WARNING in nilfs_rmdir. [1] Because the inode bitmap is corrupted, an inode with an inode number that should exist as a ".nilfs" file was reassigned by nilfs_mkdir for "file0", causing an inode duplication during execution. And this causes an underflow of i_nlink in rmdir operations. The inode is used twice by the same task to unmount and remove directories ".nilfs" and "file0", it trig... • https://git.kernel.org/stable/c/d25006523d0b9e49fd097b2e974e7c8c05bd7f54 •
CVE-2024-53685 – ceph: give up on paths longer than PATH_MAX
https://notcve.org/view.php?id=CVE-2024-53685
11 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: ceph: give up on paths longer than PATH_MAX If the full path to be built by ceph_mdsc_build_path() happens to be longer than PATH_MAX, then this function will enter an endless (retry) loop, effectively blocking the whole task. Most of the machine becomes unusable, making this a very simple and effective DoS vulnerability. I cannot imagine why this retry was ever implemented, but it seems rather useless and harmful to me. Let's remove it and... • https://git.kernel.org/stable/c/e4b168c64da06954be5d520f6c16469b1cadc069 •
