一、漏洞信息
漏洞编号:CVE-2026-52930
漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.12.33,6.18.18,6.4.0,6.6.0
CVSS评分:
BaseScore:5.5 Medium
Vector:CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:ipc/shm: serialize orphan cleanup with shm_nattch updatesshm_destroy_orphaned() walks the shm idr under shm_ids(ns).rwsem, but thatdoes not serialize all fields tested by shm_may_destroy(). In particular,shm_nattch is updated while holding shm_perm.lock, and attach paths can dothat without holding the rwsem.Do not decide that an orphaned segment is unused before taking the objectlock. Move the shm_may_destroy() check under shm_perm.lock, matching theother destroy paths, and unlock the segment when it no longer qualifiesfor removal.

原因说明填写请参考下方表格(注意:版本是否受影响和版本的原因说明必须对应,例如master版本分支受影响,那原因说明只能是受影响对应的原因之一!):

分支状态
原因说明 使用场景
受影响 正常修复 受影响且需要修复(包含升级版本修复)的漏洞;
受影响且已经修复的漏洞(历史修复PR也需要关联issue);
若因特殊原因无法修复,应修改原因说明为【不修复-特殊原因】,并在安委会备案相关情况。
受影响 漏洞仍在分析中 已关注到相关漏洞,正在处理,未明确漏洞影响和修复方案。
受影响 暂不修复-暂无解决方案或补丁 当前没有可用的修复或补救措施。【影响性分析】中应包含有关为什么没有修复或补救措施的详细说明、上游相关PR等。
受影响 不修复-超出修复范围 没有漏洞的修复计划。当版本停维、软件包宣布生命周期终止或弃用使用。
受影响 不修复-特殊原因导致不再修复 如存在其他特殊情况不修复相关漏洞,或评估后无法升级修复,应在openEuler社区安全委员会例会进行说明备案。
【影响性分析】中应包含不发布修复的详细说明、特殊情况还应有安委会会议纪要。
不受影响 不受影响-组件不存在 软件不受影响,因为易受攻击的组件不在产品中。
不受影响 不受影响-已有内置的内联控制或缓解措施 内置的内联控制或缓解措施可防止攻击者利用漏洞
不受影响 不受影响-漏洞代码不能被攻击者触发 易受攻击的组件存在,并且该组件包含易受攻击的代码。但是,易受攻击的代码的使用方式使得攻击者无法进行任何预期的攻击。
不受影响 不受影响-漏洞代码不在执行路径 易受影响的代码在执行过程中不可访问,包括产品的非预期状态。产品不使用也不执行的组件。
不受影响 不受影响-漏洞代码不存在 产品不受影响,因为漏洞背后的代码在产品中不存在。与component_not_present不同的是,有问题的组件存在,但由于某种原因(例如安全的编译器选项)使漏洞的特定代码不存在于组件中。

CVE-2026-52930

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

ipc/shm: serialize orphan cleanup with shm_nattch updates

shm_destroy_orphaned() walks the shm idr under shm_ids(ns).rwsem, but that
does not serialize all fields tested by shm_may_destroy(). In particular,
shm_nattch is updated while holding shm_perm.lock, and attach paths can do
that without holding the rwsem.

Do not decide that an orphaned segment is unused before taking the object
lock. Move the shm_may_destroy() check under shm_perm.lock, matching the
other destroy paths, and unlock the segment when it no longer qualifies
for removal.

CVE-2026-52930

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

ipc/shm: serialize orphan cleanup with shm_nattch updates

shm_destroy_orphaned() walks the shm idr under shm_ids(ns).rwsem, but that
does not serialize all fields tested by shm_may_destroy(). In particular,
shm_nattch is updated while holding shm_perm.lock, and attach paths can do
that without holding the rwsem.

Do not decide that an orphaned segment is unused before taking the object
lock. Move the shm_may_destroy() check under shm_perm.lock, matching the
other destroy paths, and unlock the segment when it no longer qualifies
for removal.
