CVE-2023-54284

CVE-2023-54284 : Linux kernel vulnerability in the media/av7110 path. The issue arises from underflow-prone length calculation in write_ts_to_decoder(), where buf[4] is user-controlled via ts_play(). The intended final length passed to av7110_ipack_instant_repack() is computed as len - (buf[4] + ...

CVE-2023-54259

CVE-2023-54259 (Linux kernel, SoundWire bus) : Affects the soundwire: bus code where an unbalanced pm_runtime_put() could underflow the usage count. The root cause is that -EACCES errors when getting pm_runtime were ignored, and a final put was performed regardless. The fix reverts a previous cha...

CVE-2023-54201

CVE-2023-54201 (RDMA/efa) in the Linux kernel fixed an incorrect resource-deallocation order when destroying QP/CQ. The patch ensures resources are deallocated in reverse allocation order; otherwise a device failure can leave the object partially destroyed, allowing a second destroy attempt that ...

CVE-2022-50816

CVE-2022-50816 affects the Linux kernel IPv6 tunneling MTU handling. Root cause: a layer could set dev->mtu to an underflowed value due to insufficient sanitization when updating MTU for ip6_gre/ip6_tnl/ipip6 tunnels. Impact described in the sources includes potential invalid skb handling and ...
