Security Vulnerabilities - CVEs Published In February 2025
In the Linux kernel, the following vulnerability has been resolved:
ima: Fix potential memory leak in ima_init_crypto()
On failure to allocate the SHA1 tfm, IMA fails to initialize and exits
without freeing the ima_algo_array. Add the missing kfree() for
ima_algo_array to avoid the potential memory leak.

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

In the Linux kernel, the following vulnerability has been resolved:
sysctl: Fix data-races in proc_dou8vec_minmax().
A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.
This patch changes proc_dou8vec_minmax() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_dou8vec_minmax() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.

In the Linux kernel, the following vulnerability has been resolved:
vlan: fix memory leak in vlan_newlink()
Blamed commit added back a bug I fixed in commit 9bbd917e0bec
("vlan: fix memory leak in vlan_dev_set_egress_priority")
If a memory allocation fails in vlan_changelink() after other allocations
succeeded, we need to call vlan_dev_free_egress_priority()
to free all allocated memory because after a failed ->newlink()
we do not call any methods like ndo_uninit() or dev->priv_destructor().
In following example, if the allocation for last element 2000:2001 fails,
we need to free eight prior allocations:
ip link add link dummy0 dummy0.100 type vlan id 100 \
egress-qos-map 1:2 2:3 3:4 4:5 5:6 6:7 7:8 8:9 2000:2001

In the Linux kernel, the following vulnerability has been resolved:
pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux()
pdesc could be null but still dereference pdesc->name and it will lead to
a null pointer access. So we move a null check before dereference.
