kernel: denial of service in tipc_conn_close

A data race flaw was found in the Linux kernel, between where con is allocated and con-sock is set. This issue leads to a NULL pointer dereference when accessing con-sock-sk in net/tipc/topsrv.c in the tipc protocol in the Linux kernel...

kernel: ipv4: Fix a data-race around sysctl_fib_sync_mem.

In the Linux kernel, the following vulnerability has been resolved: ipv4: Fix a data-race around sysctlfibsyncmem. While reading sysctlfibsyncmem, it can be changed concurrently. So, we need to add READONCE to avoid a data-race...

kernel: bpf: Fix a data-race around bpf_jit_limit.

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a data-race around bpfjitlimit. While reading bpfjitlimit, it can be changed concurrently via sysctl, WRITEONCE in doprocdoulongvecminmax. The size of bpfjitlimit is long, so we need to add a paired READONCE to avoid...

kernel: icmp: Fix a data-race around sysctl_icmp_errors_use_inbound_ifaddr.

A flaw was found in the Linux kernel's ICMP protocol. A race condition can occur when reading the sysctlicmperrorsuseinboundifaddr resource due to a missing lock, potentially impacting system stability and resulting in a denial of service...

kernel: nexthop: Fix data-races around nexthop_compat_mode.

In the Linux kernel, the following vulnerability has been resolved: nexthop: Fix data-races around nexthopcompatmode. While reading nexthopcompatmode, it can be changed concurrently. Thus, we need to add READONCE to its readers...
