net: usb: smsc75xx: Limit packet length to skb->len
562511c 
jira VULN-67489
cve CVE-2023-53125
commit-author Szymon Heidrich <szymon.heidrich@gmail.com>
commit d8b2283

Packet length retrieved from skb data may be larger than
the actual socket buffer length (up to 9026 bytes). In such
case the cloned skb passed up the network stack will leak
kernel memory contents.

commit 43ffe6c

Packet length check needs to be located after size and align_count
calculation to prevent kernel panic in skb_pull() in case
rx_cmd_a & RX_CMD_A_RED evaluates to true.

ipv6: mcast: Delay put pmc->idev in mld_del_delrec()

jira VULN-131123
cve CVE-2025-38550
commit-author Yue Haibing <yuehaibing@huawei.com>
commit ae3264a

pmc->idev is still used in ip6_mc_clear_src(), so as mld_clear_delrec()
does, the reference should be put after ip6_mc_clear_src() return.

Fixes: 63ed8de ("mld: add mc_lock for protecting per-interface mld data")

ALSA: hda/ca0132: Fix buffer overflow in add_tuning_control
473d923 
jira VULN-152898
cve CVE-2025-39751
commit-author Lucy Thrun <lucy.thrun@digital-rabbithole.de>
commit a409c60

The 'sprintf' call in 'add_tuning_control' may exceed the 44-byte
buffer if either string argument is too long. This triggers a compiler
warning.
Replaced 'sprintf' with 'snprintf' to limit string lengths to prevent
overflow.
