2025-02-26 CVE-2021-47655 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: media: venus: vdec: fixed possible memory leak issue The venus_helper_alloc_dpb_bufs() implementation allows an early return on an error path when checking the id from ida_alloc_min() which would not release the earlier buffer allocation. Move the direct kfree() from the error checking of dma_alloc_attrs() to the common fail path to ensure that allocations are released on all error paths in this function. Addresses-Coverity: 1494120 ("Resource leak")

2025-02-26 CVE-2021-47660 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()' All error handling paths lead to 'out' where many resources are freed. Do it as well here instead of a direct return, otherwise 'log', 'ra' and 'log->one_page_buf' (at least) will leak.

2025-02-12 CVE-2025-21696 Unspecified vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: mm: clear uffd-wp PTE/PMD state on mremap() When mremap()ing a memory region previously registered with userfaultfd as write-protected but without UFFD_FEATURE_EVENT_REMAP, an inconsistency in flag clearing leads to a mismatch between the vma flags (which have uffd-wp cleared) and the pte/pmd flags (which do not have uffd-wp cleared).

2025-02-12 CVE-2025-21697 Unspecified vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Ensure job pointer is set to NULL after job completion After a job completes, the corresponding pointer in the device must be set to NULL.

2025-02-12 CVE-2025-21699 Unspecified vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag Truncate an inode's address space when flipping the GFS2_DIF_JDATA flag: depending on that flag, the pages in the address space will either use buffer heads or iomap_folio_state structs, and we cannot mix the two.

2025-02-10 CVE-2024-57950 Divide By Zero vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize denominator defaults to 1 [WHAT & HOW] Variables, used as denominators and maybe not assigned to other values, should be initialized to non-zero to avoid DIVIDE_BY_ZERO, as reported by Coverity.

In the Linux kernel, the following vulnerability has been resolved: vfio/platform: check the bounds of read/write syscalls count and offset are passed from user space and not checked, only offset is capped to 40 bits, which can be used to read/write out of bounds of the device.

2025-02-10 CVE-2025-21689 NULL Pointer Dereference vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb() This patch addresses a null-ptr-deref in qt2_process_read_urb() due to an incorrect bounds check in the following: if (newport > serial->num_ports) { dev_err(&port->dev, "%s - port change to invalid port: %i\n", __func__, newport); break; } The condition doesn't account for the valid range of the serial->port buffer, which is from 0 to serial->num_ports - 1.

In the Linux kernel, the following vulnerability has been resolved: scsi: storvsc: Ratelimit warning logs to prevent VM denial of service If there's a persistent error in the hypervisor, the SCSI warning for failed I/O can flood the kernel log and max out CPU utilization, preventing troubleshooting from the VM side.
