From: Baogen Shang <baogen.shang(a)windriver.com> Run sync from the openEuler-22.03-LTS fail, so create a new PR. Just remove 3 patches from the openEuler-22.03-LTS PR, since they have been applied on SP1. Ranjan Kumar (1): scsi: mpt3sas: Perform additional retries if doorbell read returns 0 Sreekanth Reddy (2): scsi: mpt3sas: Don't change DMA mask while reallocating pools scsi: mpt3sas: Remove usage of dma_get_required_mask() API Tomas Henzl (1): scsi: mpt3sas: Fix a memory leak Wenchao Hao (1): scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add() Yang Yingliang (1): scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add() drivers/scsi/mpt3sas/mpt3sas_base.c | 69 +++++++++++++++++------- drivers/scsi/mpt3sas/mpt3sas_base.h | 1 + drivers/scsi/mpt3sas/mpt3sas_transport.c | 16 +++++- 3 files changed, 64 insertions(+), 22 deletions(-) -- 2.33.0

[PATCH OLK-6.6] Bluetooth: rfcomm: Fix null-ptr-deref in rfcomm_check_security
by Zhengchao Shao 20 Mar '24

20 Mar '24

From: Yuxuan Hu <20373622(a)buaa.edu.cn> mainline inclusion from mainline-v6.8-rc7 commit 2535b848fa0f42ddff3e5255cf5e742c9b77bb26 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YV3O CVE: CVE-2024-22099 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- During our fuzz testing of the connection and disconnection process at the RFCOMM layer, we discovered this bug. By comparing the packets from a normal connection and disconnection process with the testcase that triggered a KASAN report. We analyzed the cause of this bug as follows: 1. In the packets captured during a normal connection, the host sends a `Read Encryption Key Size` type of `HCI_CMD` packet (Command Opcode: 0x1408) to the controller to inquire the length of encryption key.After receiving this packet, the controller immediately replies with a Command Completepacket (Event Code: 0x0e) to return the Encryption Key Size. 2. In our fuzz test case, the timing of the controller's response to this packet was delayed to an unexpected point: after the RFCOMM and L2CAP layers had disconnected but before the HCI layer had disconnected. 3. After receiving the Encryption Key Size Response at the time described in point 2, the host still called the rfcomm_check_security function. However, by this time `struct l2cap_conn *conn = l2cap_pi(sk)->chan->conn;` had already been released, and when the function executed `return hci_conn_security(conn->hcon, d->sec_level, auth_type, d->out);`, specifically when accessing `conn->hcon`, a null-ptr-deref error occurred. To fix this bug, check if `sk->sk_state` is BT_CLOSED before calling rfcomm_recv_frame in rfcomm_process_rx.

[PATCH openEuler-1.0-LTS] hwrng: core - Fix page fault dead lock on mmap-ed hwrng
by Yi Yang 20 Mar '24

20 Mar '24

From: Herbert Xu <herbert(a)gondor.apana.org.au> stable inclusion from stable-v4.19.307 commit eafd83b92f6c044007a3591cbd476bcf90455990 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I99JR3 CVE: CVE-2023-52615 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 78aafb3884f6bc6636efcc1760c891c8500b9922 upstream. There is a dead-lock in the hwrng device read path. This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page fault triggers a recursive read which then dead-locks. Fix this by using a stack buffer when calling copy_to_user.

[PATCH openEuler-1.0-LTS-o] hwrng: core - Fix page fault dead lock on mmap-ed hwrng
by Yi Yang 20 Mar '24

20 Mar '24

From: Herbert Xu <herbert(a)gondor.apana.org.au> stable inclusion from stable-v4.19.307 commit eafd83b92f6c044007a3591cbd476bcf90455990 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I99JR3 CVE: CVE-2023-52615 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 78aafb3884f6bc6636efcc1760c891c8500b9922 upstream. There is a dead-lock in the hwrng device read path. This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page fault triggers a recursive read which then dead-locks. Fix this by using a stack buffer when calling copy_to_user.
