CVE-2023-53645

CVE-2023-53645 : Linux kernel patch fixes a use-after-free risk in BPF non-owning references by making bpf_refcount_acquire fallible. The fix changes the implementation (bpf_refcount_acquire_impl) to use refcount_inc_not_zero and return KF_RET_NULL, preventing increment on a possibly freed object...

CVE-2022-50522

The CVE-2022-50522 entry corresponds to a Linux kernel issue in mcb-parse (chameleon_parse_gdd). When mcb_device_register() returns an error, the refcount for the bus and device name is leaked. The fix adds a put_device() to relinquish the reference so resources can be released during mcb_release...

In the Linux kernel, the following vulnerability has been resolved: mcb: mcb-parse: fix error handing in chameleonparsegdd If mcbdeviceregister returns error in chameleonparsegdd, the refcount of bus and device name are leaked. Fix this by calling putdevice to give up the reference, so they can b...

CVE-2022-50520 drm/radeon: Fix PCI device refcount leak in radeon_atrm_get_bios()

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Fix PCI device refcount leak in radeonatrmgetbios As comment of pcigetclass says, it returns a pcidevice with its refcount increased and decreased the refcount for the input parameter @from if it is not NULL. If we...

CVE-2022-50520

CVE-2022-50520 affects the Linux kernel's DRM Radeon path, where radeon_atrm_get_bios() leaked a PCI device refcount due to a missing pci_dev_put() when breaking the loop. The issue arises because pci_get_class() may return a pci_device with a retained reference, and if the loop is exited with pd...
