CVE-2022-49080

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix mpolnew leak in sharedpolicyreplace If mpolnew is allocated but not used in restart loop, mpolnew will be freed via mpolput before returning to the caller. But refcnt is not initialized yet, so mpolput could not...

CVE-2022-49080 mm/mempolicy: fix mpol_new leak in shared_policy_replace

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix mpolnew leak in sharedpolicyreplace If mpolnew is allocated but not used in restart loop, mpolnew will be freed via mpolput before returning to the caller. But refcnt is not initialized yet, so mpolput could not...

CVE-2022-49080

CVE-2022-49080 affects the Linux kernel mempolicy path, where allocating mpol_new and leaking it can occur if a restart loop drops sp->lock before refcnt is initialized. The issue arises in shared_policy_replace when mempolicy is updated on a shared shmem file under concurrent access, potentia...

CVE-2021-47656 jffs2: fix use-after-free in jffs2_clear_xattr_subsystem

In the Linux kernel, the following vulnerability has been resolved: jffs2: fix use-after-free in jffs2clearxattrsubsystem When we mount a jffs2 image, assume that the first few blocks of the image are normal and contain at least one xattr-related inode, but the next block is abnormal. As a result...

CVE-2021-47651

Summary : CVE-2021-47651 involves the Linux kernel driver path soc: qcom: rpmpd, where data->domains could be NULL if an allocation fails. The vulnerability stems from not validating a possible NULL return from devm_kcalloc, risking a NULL pointer dereference later. The public description indi...

CVE-2021-47651 soc: qcom: rpmpd: Check for null return of devm_kcalloc

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: rpmpd: Check for null return of devmkcalloc Because of the possible failure of the allocation, data-domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better ...

CVE-2021-47649

The CVE-2021-47649 entry concerns a Linux kernel udmabuf issue where ubuf->pagecount could be zero if user-space passes list.size==0, leading kmalloc_array() to return ZERO_PTR and triggering a GPF in sg_alloc_append_table_from_pages(). The vulnerability arises from pagecount derived from user...
