Description:
Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to disclose potentially sensitive information or to cause a DoS (Denial of Service).
1) An error exists within the "snd_seq_oss_synth_make_info()" function in sound/core/seq/oss/seq_oss_synth.c. This can be exploited to disclose potentially sensitive memory by passing an invalid device number to the vulnerable function.
2) An error exists within the VFS lookup functionality when handling deleted directories. This can be exploited to install a child dentry for a deleted directory and cause a crash on certain filesystems (e.g. UBIFS).
3) An error within the "shmem_delete_inode()" function in mm/shmem.c can be exploited to trigger a kernel BUG via certain file operations.
Vulnerabilities #1 and #2 are reported in versions prior to 2.6.26.2. Vulnerability #3 is reported in versions prior to 2.6.26.1.
