kernel: Linux kernel: Memory leak in wilc1000 Wi-Fi driver causes Denial of Service

A flaw was found in the Linux kernel's wilc1000 Wi-Fi driver. A local attacker with low privileges could exploit a memory leak in the wilcmacxmit function, which fails to free a socket buffer skb under certain conditions. This resource exhaustion vulnerability can lead to a Denial of Service DoS ...

kernel: wifi: ath9k: hif_usb: Fix use-after-free in ath9k_hif_usb_reg_in_cb()

A flaw was found in the ath9k USB Wi-Fi driver in the Linux kernel. In certain conditions within the ath9khifusbregincb path, a socket buffer skb may be freed prematurely and then freed again on an error path, leading to a use-after-free condition. Additionally, failure to allocate a new skb can...

USN-6441-2 linux-gcp-5.4 vulnerabilities

Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service host system crash or...

USN-6440-1 linux, linux-aws, linux-azure, linux-azure-4.15, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle vulnerabilities

Seth Jenkins discovered that the Linux kernel did not properly perform address randomization for a per-cpu memory management structure. A local attacker could use this to expose sensitive information kernel memory or in conjunction with another kernel vulnerability. CVE-2023-0597 It was discovere...

kernel: denial of service problem in net/unix/diag.c

A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unixdiaggetexact in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows a local user to crash or potentially cause a denial of service...

AZL-31271 CVE-2023-42754 affecting package kernel for versions less than 5.15.135.1-2

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...
