Linux: >> Linux Kernel >> 5.10.164 Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: brcmnand: Fix potential out-of-bounds access in oob write
When the oob buffer length is not in multiple of words, the oob write
function does out-of-bounds read on the oob source buffer at the last
iteration. Fix that by always checking length limit on the oob buffer
read and fill with 0xff when reaching the end of the buffer to the oob
registers.

In the Linux kernel, the following vulnerability has been resolved:
ARM: dts: exynos: Use Exynos5420 compatible for the MIPI video phy
For some reason, the driver adding support for Exynos5420 MIPI phy
back in 2016 wasn't used on Exynos5420, which caused a kernel panic.
Add the proper compatible for it.

In the Linux kernel, the following vulnerability has been resolved:
cpufreq: davinci: Fix clk use after free
The remove function first frees the clks and only then calls
cpufreq_unregister_driver(). If one of the cpufreq callbacks is called
just before cpufreq_unregister_driver() is run, the freed clks might be
used.

In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: unmap and remove csa_va properly
Root PD BO should be reserved before unmap and remove
a bo_va from VM otherwise lockdep will complain.
v2: check fpriv->csa_va is not NULL instead of amdgpu_mcbp (christian)

In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: DR, fix memory leak in mlx5dr_cmd_create_reformat_ctx
when mlx5_cmd_exec failed in mlx5dr_cmd_create_reformat_ctx, the memory
pointed by 'in' is not released, which will cause memory leak. Move memory
release after mlx5_cmd_exec.

In the Linux kernel, the following vulnerability has been resolved:
Input: raspberrypi-ts - fix refcount leak in rpi_ts_probe
rpi_firmware_get() take reference, we need to release it in error paths
as well. Use devm_rpi_firmware_get() helper to handling the resources.
Also remove the existing rpi_firmware_put().

In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: mtk_drm_crtc: Add checks for devm_kcalloc
As the devm_kcalloc may return NULL, the return value needs to be checked
to avoid NULL poineter dereference.

In the Linux kernel, the following vulnerability has been resolved:
net: bcmgenet: Add a check for oversized packets
Occasionnaly we may get oversized packets from the hardware which
exceed the nomimal 2KiB buffer size we allocate SKBs with. Add an early
check which drops the packet to avoid invoking skb_over_panic() and move
on to processing the next packet.

In the Linux kernel, the following vulnerability has been resolved:
blk-crypto: make blk_crypto_evict_key() more robust
If blk_crypto_evict_key() sees that the key is still in-use (due to a
bug) or that ->keyslot_evict failed, it currently just returns while
leaving the key linked into the keyslot management structures.
However, blk_crypto_evict_key() is only called in contexts such as inode
eviction where failure is not an option. So actually the caller
proceeds with freeing the blk_crypto_key regardless of the return value
of blk_crypto_evict_key().
These two assumptions don't match, and the result is that there can be a
use-after-free in blk_crypto_reprogram_all_keys() after one of these
errors occurs. (Note, these errors *shouldn't* happen; we're just
talking about what happens if they do anyway.)
Fix this by making blk_crypto_evict_key() unlink the key from the
keyslot management structures even on failure.
Also improve some comments.

f2fs: fix to avoid use-after-free for cached IPU bio

The root cause is: after cp_error is set, f2fs_submit_merged_ipu_write()
in f2fs_write_single_data_page() tries to flush IPU bio in cache, however
f2fs_submit_merged_ipu_write() missed to check validity of @bio parameter,
result in submitting random cached bio which belong to other IO context,
then it will cause use-after-free issue, fix it by adding additional
validity check.
