02 Apr 2020 — An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4. Se detectó un problema en la función slc_bump en el archivo drivers/net/can/slcan.c en el kernel de Linux versión 3.16 hasta la versión 5.6.2.

https://notcve.org/view.php?id=CVE-2020-8835
30 Mar 2020 — In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780) En el kernel de Linux versiones 5.5.0 y más recientes, el verificador bpf (ker... • https://github.com/zilong3033/CVE-2020-8835 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

24 Mar 2020 — In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls. En el kernel de Linux versiones anteriores a 5.5.8, la función get_raw_socket en el archivo drivers/vhost/net.c carece de una comprobación de un campo sk_family, que podría permitir a atacantes desencadenar una corrupción de pila del kernel por medio de llamadas de sistema diseñadas.

25 Feb 2020 — An issue was discovered in the Linux kernel 5.4 and 5.5 through 5.5.6 on the AArch64 architecture. It ignores the top byte in the address passed to the brk system call, potentially moving the memory break downwards when the application expects it to move upwards, aka CID-dcde237319e6. This has been observed to cause heap corruption with the GNU C Library malloc implementation.
