SUSE CVE-2023-52872

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: fix race condition in status line change on dead connections gsmcleanupmux cleans up the gsm by closing all DLCIs, stopping all timers, removing the virtual tty devices and clearing the data queues. This procedure,...

CVE-2021-47441

In the Linux kernel, the following vulnerability has been resolved: mlxsw: thermal: Fix out-of-bounds memory accesses Currently, mlxsw allows cooling states to be set above the maximum cooling state supported by the driver: cat /sys/class/thermal/thermalzone2/cdev0/type mlxswfan cat...

CVE-2021-47246

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix page reclaim for dead peer hairpin When adding a hairpin flow, a firmware-side send queue is created for the peer net device, which claims some host memory pages for its internal ring buffer. If the peer net device...

CVE-2023-52828

In the Linux kernel, the following vulnerability has been resolved: bpf: Detect IP == ksym.end as part of BPF program Now that bpfthrow kfunc is the first such call instruction that has noreturn semantics within the verifier, this also kicks in dead code elimination in unprecedented ways. For one...

SUSE CVE-2021-47248

In the Linux kernel, the following vulnerability has been resolved: udp: fix race between close and udpabort Kaustubh reported and diagnosed a panic in udpliblookup. The root cause is udpabort racing with close. Both racing functions acquire the socket lock, but udpv6destroysock release it before...

CVE-2021-47441

CVE-2021-47441 concerns the Linux kernel mlxsw thermal driver. The issue arises when cooling state is set above the driver’s maximum state (e.g., cur_state=18 while max_state=10), which triggers out-of-bounds memory accesses in thermal statistics code. The thermal maintainer indicates it is the d...
