In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: validate default EEPROM firmware size The default EEPROM firmware is parsed and copied as a full EEPROM without checking its length. A truncated file can make the driver read beyond the firmware buffer during...

In the Linux kernel, the following vulnerability has been resolved: ipmi: ipmb: validate write message length ipmb write read message fields before validating the length byte. A zero or short write can read uninitialized stack bytes. A length smaller than the SMBus header underflows the block wri...

In the Linux kernel, the following vulnerability has been resolved: net/smc: stop killed, freed and out of sync sharing a byte The three connection state flags are single-bit bitfields, so they occupy one byte of struct smc connection and every store to one is a read-modify-write of the other two...

In the Linux kernel, the following vulnerability has been resolved: NFSD: Prevent client use-after-free during delegation revoke A delegation stateid holds only a bare pointer to its owning nfs4 client and does not keep it alive. The client survives its stateids only because destroy client drains...

In the Linux kernel, the following vulnerability has been resolved: nfsd: check client ownership when cancelling a copy-notify stateid On the OFFLOAD CANCEL path clp != NULL, manage cpntf state freed the target cpntf state without checking ownership. The lookup key st-si opaque.so id is allocated...

In the Linux kernel, the following vulnerability has been resolved: libceph: reject buckets with mismatched CRUSH ids crush decode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from the decoded bucket id. A malformed map can therefore make one bucke...
