UBUNTU-CVE-2022-50781

In the Linux kernel, the following vulnerability has been resolved: amdgpu/pm: prevent array underflow in vega20odneditdpmtable In the PPODEDITVDDCCURVE case the "inputindex" variable is capped at 2 but not checked for negative values so it results in an out of bounds read. This value comes from...

CVE-2023-54081

In the Linux kernel, the following vulnerability has been resolved: xen: speed up grant-table reclaim When a grant entry is still in use by the remote domain, Linux must put it on a deferred list.

CVE-2023-54081

CVE-2023-54081 affects the Linux kernel Xen grant-table reclaim path. When a grant entry is still in use by the remote domain, the VM may accumulate a large deferred-list, causing a severe memory leak and potential VM freeze, notably in Qubes OS due to GUI/window handling constraints. The fix mak...

CVE-2022-50781

CVE-2022-50781 (Linux kernel, amdgpu driver) : The issue occurs in amdgpu/pm within the Vega 20 DPM table handling (PP_OD_EDIT_VDDC_CURVE). The root cause is that input_index is capped at 2 but not checked for negative values, leading to an out-of-bounds read when the value is supplied by user sp...

CVE-2022-50739

The connected docs confirm CVE-2022-50739 affects the Linux kernel's ntfs3 filesystem. Root cause: missing validation of inode's i_op pointer after reading the Root directory MFT, which can cause a NULL pointer dereference when mounting an image with a malformed Root directory MFT record. The fix...

CVE-2023-54061 x86: fix clear_user_rep_good() exception handling annotation

In the Linux kernel, the following vulnerability has been resolved: x86: fix clearuserrepgood exception handling annotation This code no longer exists in mainline, because it was removed in commit d2c95f9d6802 "x86: don't use REPGOOD or ERMS for user memory clearing" upstream. However, rather tha...
