Descriptions

In the Linux kernel, the following vulnerability has been resolved: ASoC: stm32: spdifrx: fix dma channel release in stm32_spdifrx_remove In case of error when requesting ctrl_chan DMA channel, ctrl_chan is not
null. So the release of the dma channel leads to the following issue:
[ 4.879000] st,stm32-spdifrx 500d0000.audio-controller:
dma_request_slave_channel error -19
[ 4.888975] Unable to handle kernel NULL pointer dereference
at virtual address 000000000000003d
[...]
[ 5.096577] Call trace:
[ 5.099099] dma_release_channel+0x24/0x100
[ 5.103235] stm32_spdifrx_remove+0x24/0x60 [snd_soc_stm32_spdifrx]
[ 5.109494] stm32_spdifrx_probe+0x320/0x4c4 [snd_soc_stm32_spdifrx] To avoid this issue, release channel only if the pointer is valid.

Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service or possibly execute arbitrary code. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
