Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fragment transmission helper function failing to propagate the SKBFLSHAREDFRAG bit. This coul...

SUSE CVE-2026-43495

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: validate portcount against message length in t7xxportenummsghandler t7xxportenummsghandler uses the modem-supplied portcount field as a loop bound over portmsg-data without checking that the message buffer contai...

CVE-2026-43501

In the Linux kernel, the following vulnerability has been resolved: ipv6: rpl: reserve maclen headroom when recompressed SRH grows ipv6rplsrhrcv decompresses an RFC 6554 Source Routing Header, swaps the next segment into ipv6hdr-daddr, recompresses, then pulls the old header and pushes the new on...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: esp: fix bad handling of pages from pagepool When the skb is reorganized during espoutput !esp-inline, the pages coming from the original skb fragments are supposed to be released back to the system through putpage. But if t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fixed the Rx DMA data size and skboverpanic issue. The function managetrxbufcfg aligns the DMA data size of the RX buffer to be a multiple of 64. As a result, a packet slightly larger than mtu+14, for example, 1536...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: net: sched: Fixed the use of “skb” after it is passed to qdiscenqueue. We cannot use “skb” again after passing it to qdiscenqueue. This is essentially identical to commit 2f09707d0c97 “schsfb: Also store skblen before calling chi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: iwlwifi: mei: fix potential NULL-ptr dereference after clone If cloning an SKB object fails, do not attempt to use it. Instead, return an error code as if you are passing it along. Coverity CID: 1503456...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: xilinx: axienet: Fixed BQL accounting for multi-BD TX packets. When a TX packet spans multiple buffer descriptors scatter-gather, axienetfreetxchain sums the actual length of each BD from the descriptor status into an...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: l2tp: The correct message length must be passed to ip6 AppendData. l2tpip6sendmsg needs to avoid accounting for the transport header twice when splicing more data into an already partially-occupied skbuff. To address this issu...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Wifi: ath9k: hifusb: Clean up skbs if ath9khifusbrxstream fails Syzkaller detected a memory leak of skbs in ath9khifusbrxstream. While processing skbs in ath9khifusbrxstream, the already allocated skbs in skbpool are not freed if...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: bonding: Do not assume that the skbmacheader is set. Drivers must not assume that skbs have their macheader set. skb-data is all that is needed. bonding seems to be one of the last vulnerabilities detected by syzbot: WARNING:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mlx5: Fixed a leak in skb during fifo resync and push operations. During the ptp resync operation, SKBs were popped from the fifo, but they were never freed either by napiconsume or by devkfreeskbany. Added a call to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: can: dev: cangetechoskb: prevents calling kfreeskb in a hard IRQ context. If a driver calls cangetechoskb during a hardware IRQ which is often, but not always the case, the WARNONinirq in net/core/skbuff.cskbreleaseheadstate migh...
