CVE-2023-53239

CVE-2023-53239 affects the Linux kernel component drm/msm/mdp5. The vulnerability arises because kzalloc() may return NULL and code did not reliably handle this, risking a NULL pointer dereference. The advisories indicate a patch was added to validate the kzalloc return value to avoid dereferenci...

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...

CVE-2022-50286 ext4: fix delayed allocation bug in ext4_clu_mapped for bigalloc + inline

In the Linux kernel, the following vulnerability has been resolved: ext4: fix delayed allocation bug in ext4clumapped for bigalloc + inline When converting files with inline data to extents, delayed allocations made on a file system created with both the bigalloc and inline options can result in...

CVE-2022-50286

The CVE-2022-50286 issue affects the Linux kernel ext4 file system in scenarios where bigalloc and inline options are used simultaneously. The root cause is in ext4_clu_mapped: when converting inline-stored data to extents, the code may search the (non-existent) extent tree to decide if a block s...

CVE-2022-50276 power: supply: fix null pointer dereferencing in power_supply_get_battery_info

In the Linux kernel, the following vulnerability has been resolved: power: supply: fix null pointer dereferencing in powersupplygetbatteryinfo when kmalloc fail to allocate memory in kasprintf, propname will be NULL, strcmp called by ofgetproperty will cause null pointer dereference. So return...

CVE-2022-50271

CVE-2022-50271 affects the Linux kernel’s vhost/vsock code. The issue arises when copying large files over SFTP over vsock, where data sizes commonly reach 32 kB and kmalloc may allocate many 32 kB chunks, leading to a page allocation failure (example: vhost-5837). The root cause is an inefficien...

CVE-2022-50271 vhost/vsock: Use kvmalloc/kvfree for larger packets.

In the Linux kernel, the following vulnerability has been resolved: vhost/vsock: Use kvmalloc/kvfree for larger packets. When copying a large file over sftp over vsock, data size is usually 32kB, and kmalloc seems to fail to try to allocate 32 32kB regions. vhost-5837: page allocation failure:...

CVE-2022-50269

CVE-2022-50269 affects the Linux kernel (drm/vkms). Root cause: vkms_init() allocates a config with kmalloc and may leak if vkms_create() fails, since the return value isn’t checked before exiting. Impact: local attacker could cause memory leak during vkms module initialization. The fixed descrip...

CVE-2023-53174

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix possible memory leak if deviceadd fails If deviceadd returns error, the name allocated by devsetname needs be freed. As the comment of deviceadd says, putdevice should be used to decrease the reference count in th...

DEBIAN-CVE-2022-50251

In the Linux kernel, the following vulnerability has been resolved: mmc: vub300: fix return value check of mmcaddhost mmcaddhost may return error, if we ignore its return value, the memory that allocated in mmcallochost will be leaked and it will lead a kernel crash because of deleting not added...

CVE-2022-50245

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...
