CVE-2021-4460

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix UBSAN shift-out-of-bounds warning If getnumsdmaqueues or getnumxgmisdmaqueues is 0, we end up doing a shift operation where the number of bits shifted equals number of bits in the operand. This behaviour is...

UBUNTU-CVE-2023-53495

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mvpp2main: fix possible OOB write in mvpp2ethtoolgetrxnfc rules is allocated in ethtoolgetrxnfc and the size is determined by rulecnt from user space. So rulecnt needs to be check before using rules to avoid OOB...

CVE-2023-53501 iommu/amd/iommu_v2: Fix pasid_state refcount dec hit 0 warning on pasid unbind

In the Linux kernel, the following vulnerability has been resolved: iommu/amd/iommuv2: Fix pasidstate refcount dec hit 0 warning on pasid unbind When unbinding pasid - a race condition exists vs outstanding page faults. To prevent this, the pasidstate object contains a refcount. set to 1 on pasid...

CVE-2023-53495

The CVE-2023-53495 issue in the Linux kernel concerns the mvpp2 ethernet driver (mvpp2_main). A fix was implemented to prevent an OOB write in mvpp2_ethtool_get_rxnfc() by validating rule_cnt before iterating over rules allocated in ethtool_get_rxnfc(). The underlying problem was that the rules b...

CVE-2022-50457 mtd: core: Fix refcount error in del_mtd_device()

In the Linux kernel, the following vulnerability has been resolved: mtd: core: Fix refcount error in delmtddevice delmtddevice will call ofnodeput to mtdgetofnodemtd, which is mtd-dev.ofnode. However, memset&mtd-dev, 0 is called before ofnodeput. As the result, ofnodeput won't do anything in...
