CVE-2022-50293

CVE-2022-50293 affects the Linux kernel btrfs subsystem. When dropping file extent items for a range, ENOMEM could trigger a BUG_ON() path in btrfs_drop_extents(); the fix replaces those BUG_ON()s with proper transaction abort and error return handling. This means that instead of halting the tran...

CVE-2023-53211

The CVE-2023-53211 issue affects the Linux kernel’s driver core, where a struct acpi_pld_info *pld was not freed before returning on allocation failure, risking a memory leak. The fix adds ACPI_FREE() calls to release the allocated memory before the function exits. Connected documents confirm thi...

DEBIAN-CVE-2022-50242

In the Linux kernel, the following vulnerability has been resolved: drivers: net: qlcnic: Fix potential memory leak in qlcnicsriovinit If vp alloc failed in qlcnicsriovinit, all previously allocated vp needs to be freed...

CVE-2023-53181 dma-buf/dma-resv: Stop leaking on krealloc() failure

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking on krealloc failure Currently dmaresvgetfences will leak the previously allocated array if the fence iteration got restarted and the kreallocarray fails. Free the old array by hand, and make sure we...

In the Linux kernel, the following vulnerability has been resolved: igb: Do not free qvector unless new one was allocated Avoid potential use-after-free condition under memory pressure. If the kzalloc fails, qvector will be freed but left in the original adapter-qvectorvidx array position...

CVE-2022-50245

CVE-2022-50245 concerns a Linux kernel issue in the rapidio driver where a UAF can occur if kfifo_alloc() fails during mport_cdev_open(). The fix removes priv from the chdev->file_list before freeing it to prevent traversal from accessing a freed object (the smatch warning reference). Affected...

CVE-2022-50245 rapidio: fix possible UAF when kfifo_alloc() fails

In the Linux kernel, the following vulnerability has been resolved: rapidio: fix possible UAF when kfifoalloc fails If kfifoalloc fails in mportcdevopen, goto errfifo and just free priv. But priv is still in the chdev-filelist, then list traversal may cause UAF. This fixes the following smatch...
